The parameters of high-evoked activity of the human brain during the perception of Kanizsa figures in various cognitive tasks has been investigated. Wavelet analysis of EEG has been demonstrated that the perception of subjective contours associated with gamma responses (30-90 Hz) in different areas of the cortex to the specific spatio-temporal patterns. This pattern indicates the formation of fronto-centro-parietal neocortex system interactions, providing the perception of distributed information.
